Currently, air purifiers are becoming essential household appliances in the living spaces of every Vietnamese family. Therefore, in addition to choosing a suitable air purifier for your family, you also need to know some tips for using air purifiers to ensure maximum effectiveness and durability.
1. Consider choosing the appropriate power for the air purifier based on the usage space
The first and most crucial factor directly affecting the effectiveness of an air purifier is its power. Avoid using a purifier with a smaller filtering area, as it won't be as effective in eliminating bacteria and viruses at their source.
If the purifier operates at low power, air filtration will take longer. On the other hand, running the purifier at the highest setting consumes more electricity.

2. Pay attention to the correct placement of the machine
Improper placement of the air purifier can reduce its operational efficiency. Typically, air purifiers have 3 air intake openings, 2 on the sides and 1 at the bottom. Therefore, it's recommended to position the machine at least 30cm away from objects like wardrobes and chairs to ensure smooth airflow.
If your living space has air conditioning, place the purifier under the air conditioning vent. This optimizes air circulation, enhancing the purifier's efficiency. When the air purifier is in operation, it's advisable to keep doors closed to prevent the escape of ions.
3. Use the machine's functions correctly
Most modern air purifiers come with technology to eliminate bacteria and mold within a specific timeframe, usually between 4 to 6 hours. Therefore, it's crucial to run the machine during this period to ensure clean and healthy air.
Additionally, pay attention to the following issues:
- Functions running the fan at low and medium airflow are suitable for daily air filtering when the room air is not too dirty.
- The fan function at the highest airflow level should only be used for polluted air due to prolonged non-use, rooms with high bacteria and mold presence.
- With smart modes in high-end air purifiers like Econavi and Inverter, you get notifications when the air is clean and automatic pauses to save energy efficiently, providing high convenience.
- Functions generating ozone and negative ions are beneficial for health.

4. Pay attention to regularly clean filters and air filter membranes
Regularly clean filters and air filter membranes to enhance the efficient operation of the air purifier. The air filter membranes are usually located at the back of the machine, so you can use your hands to remove them. Use a dust vacuum or a small brush for cleaning to keep the membranes clean and functioning optimally. During usage, clean the filter membranes every 1-2 months and replace them every 2 years to ensure the machine operates effectively.
